用类建立链表出现的问题，求解各位高手？

#include <iostream>
using namespace std;
class list{
    public:
       int data;
       list *next;
       list(){}
      ~list(){}
       static list L[100];
       int length;
};

void creat();
void insert();
void deletelist();
void print();
void creat()
{
    int n;
    int a;
    cin>>a;//输入头结点的数据
    list::L[0].data=a;
    cin>>n;//输入要创建节点的个数
    list::length=n;
    for(int i=0;i<n;i++)
    {
        int b[100];
        list::L[i].next=list::L[i+1];
        cin>>b[i];
        list::L[i+1].data=b[i];
        
    }
}

void print()
{
    for(int i=0;i<list::length;i++)
    {
        cout<<list::L[i].data<<endl;
    }
}

void main()
{
   
    creat();
    print();
}
